deploying channels with nginx
I have deployed django with nginx following the tutorials in digital ocean. Then I blindly followed the section "Example Setup" in the channels document after installation. My confusions are: When setting up the configuration file for supervisor, it says to set the directory as directory=/my/app/path Should I write down the path where the manage.py is or the path where the settings.py is? When I reload nginx after changing nginx configuration file, I get an error saying that host not found in upstream "channels-backend" in /etc/nginx/sites-enabled/mysite:18 nginx: configuration file /etc/nginx/nginx.conf test failed I did replace "mysite" by the name of my website. I had another error earlier saying that no live upstreams while connecting to upstream but could not recreate the situation. I am new to using the channels, so any additional information on upstream would be helpful. Please let me know if I need to provide more information. -
data passing by one to one field in Django
I have two models Employee and myCustomeUser in my Django project. My models.py: class myCustomeUser(AbstractUser): username = models.CharField(default="abcdef", max_length=150, unique="True") password = models.CharField(default="12345", max_length=150) is_Employee = models.BooleanField(default=False) is_Inspector = models.BooleanField(default=False) is_IndustryOwner = models.BooleanField(default=False) is_Admin = models.BooleanField(default=False) class Employee(models.Model): user = models.OneToOneField(myCustomeUser, on_delete=models.CASCADE, primary_key=True, related_name='releted_user') extraField = models.TextField(blank=True) Now I am trying to entry an Employee's data with views.py like this: Employee_obj = Employee.objects.create(releted_user.username=this_username, releted_user.password=this_password, releted_user.is_Employee=True) Employee_obj.save() But It shows error like this: Employee_obj = Employee.objects.create(releted_user.username=this_username, releted_user.password=this_password, releted_user.is_Employee=True) ^ SyntaxError: expression cannot contain assignment, perhaps you meant "=="? How can I solve this problem? Mainly I need to save any employee's data by Employee.objects.create() -

Django: Create an editable form for each instance within a queryset all in one page?
Sorry if this is too much code, but I believe it is all relevant to the question at hand. Long story short, on my series_detail page, all episodes belonging to each series is shown, as well as forms to add a new episode or edit an existing one. The edit episode form, however, requires an instance, which always returns the very first object of the episodes queryset. This is presumably because of the .first(), but I used this since you can only have one object passed as an instance. What I am trying to achieve is: after showing the edit modal next to each episode, show the instance of each episode instead of only the first episode. save only that episode's instance after the form is filled achieve this without redirecting to an edit page models.py class Series(models.Model): name = models.CharField(max_length=100) class Episode(models.Model): series = models.ForeignKey(Series, on_delete=models.CASCADE) name = models.CharField(max_length=100) episode_no = models.IntegerField(null=True) description = models.TextField(max_length=500) image = models.ImageField(upload_to='pics/episodes',) forms.py class EpisodeForm(forms.ModelForm): name = forms.CharField() description = forms.CharField(widget=forms.Textarea, required=False) episode_no = forms.IntegerField() class Meta: model = Episode fields = ['name', 'description', 'episode_no' ,'image'] views.py def series_detail(request, pk): try: series = Series.objects.get(pk=pk) except: return render(request, 'error_404.html') episodes = Episode.objects.filter(series=series).first() if request.method … -

Why does my Django Model not work correctly?
Currently making a basic django project, following a well set out tutorial off youtube. All's going well and I usually try to debug isses myself and I wouldn't be asking if i was stuck. Issue: This code is meant to check the image size onces it's reuploaded and then format to make it square but looking at the image linked, this isnt the case. Is my code wrong? is there another way to check and validate images?

Catching classes that do not inherit from BaseException is not allowed with Redis in Django Rest Framework
so i'm working on a small DRF application, and I've implemented a custom config backend using redis: class RedisBackend(ConfigBackend): CONFIG_SET = Config.objects if "migrate" not in sys.argv else MagicMock() def __init__(self): ip = settings.CONFIG['REDIS']['HOST'] port = settings.CONFIG['REDIS']['PORT'] db = settings.CONFIG['REDIS']['DB'] password = settings.CONFIG['REDIS']['PASSWORD'] from redis import Redis self.redis = Redis(host=ip, port=port, db=db, password=password) # other methods omitted for brevity It all works fine until I quit the server with CTRL-C, at which point, I get this rather unsavoury exception: Exception ignored in: <bound method Connection.__del__ of Connection<host=localhost,port=6379,db=0>> Traceback (most recent call last): File "E:\Programming\programs\anaconda\lib\site-packages\redis\connection.py", line 537, in __del__ File "E:\Programming\programs\anaconda\lib\site-packages\redis\connection.py", line 667, in disconnect TypeError: catching classes that do not inherit from BaseException is not allowed I have no idea what I can do to fix this.

Running untrusted code (Python-as-a-Service)
I would like to create a simple Python-as-a-Service service. This means the python code which executes the first http request does not trust the python code which executes the second http request. But both should be executed in the same interpreter to avoid constant starting/stopping of the interpreter. How could I clean up after the first http request was run and before the second http request gets executed. I would like to use Django for this, but AFAIK this does not matter much for the current question. -
How to load static file from JavaScript in Django?
Hello so I have been trying to play an audio element in my Django app and controlling it using JavaScript. I was trying to play the audio from localhost, but I got the following errors: And I guess it's because I made a mistake in loading the audio file in my JS code. import AudioPlayer from './AudioPlayer.js'; const audioPlayer = new AudioPlayer('.audioPlayer', [ {url: '../music/rainfall.mp3', name: 'Alleviating Rainfall'}, ]); I think I did wrong on the url: part so django does not load my mp3 file and serve it from the server. So my question is, how can I load static audio file in Django from JS? I know for HTML it's {% static "[filepath]" %} but what's for JS?? Since the JS itself is a static file..

Purpose and use of Wagtail/Django template tags of the form {% block body_class %}template-homepage{% endblock %}
In the Wagtail docs (Your first Wagtail site) we are told to create a homepage.html template as follows: {% extends "base.html" %} {% load wagtailcore_tags %} {% block body_class %}template-homepage{% endblock %} {% block content %} {{ page.body|richtext }} {% endblock %} In the above code, what is that tag {% block body_class %}template-homepage{% endblock %} supposed to be doing? I can't find any mention of it in the text of the tutorial. The tutorial goes on to instruct us to create two more templates, blog_index_page and blog_page templates, both of which are to contain {% block body_class %} tags. Again, I can find no mention at all of those lines in the docs, let alone an explanation of how they might be used/modified. A search for "body_class" in the docs finds only the three code blocks just mentioned, and one other mention: in the version 1.2 release notes, under 'What's new — Minor features' the notation: "Simplified body_class in default homepage template." Any insight as to what I'm supposed to do with these tags? What special meaning, if any, does the tag-enclosed text have in the tutorial templates (for example, "template-homepage" in the code above)? -
Is there a page or an explanation of django testing functions?
I am looking at some tutorials on django testing from django.test import TestCase from .forms import ItemForm class TestItemForm(TestCase): def test_item_name_is_required(self): form = ItemForm({'name': ''}) self.assertFalse(form.is_valid()) self.assertIn('name', form.errors.keys()) self.assertEqual(form.errors['name'][0], 'This field is required.') I understand the importing and the class with it's parameters. I am struggling to understand the .assertXXX(). I tried looking in the documentation for django, for these functions and all I get are examples of them being used, not explanations of what they do. Then I went to GitHub to try and look under the tests folder for what the tests could potentially do and I do not fully understand their code. for example I understand that .assertEqual(<first>, <second>) compares the two parameters and checks if they are equal.

PS The "name" and "surname" fields are in Therapist class (which inherits them from user.py). In TherapistProfile the field is written as "user". I kinda know the logic: I need to split the sentence into words by space and search each word in each field of each object (if you … -
Django how to limit template to only two posts
